The true answer to the question I posed in the title is, "We don't know." Like everyone else, my mind went immediately to St. Francis of Assisi. I thought, "Interesting name for the first Jesuit Pope." But a little later someone reminded me of the great Jesuit missionary, St. Francis Xavier. Later still, another friend, as well as a brother deacon, asked, "What about St. Francis de Sales?"

Before discerning his vocation to priesthood and religious life, a young Jorge Mario Bergoglio studied to become a chemist, earning a master's degree in the subject from the University of Buenos Aires. Hence, he is familiar with the term poly- or multivalence, which is a term that is also used in logic, music, and medicine. As a non-scientist (but one who has studied logic), as I grasp it, in chemistry a "valence" refers to the number of valence bonds a given atom has formed, or can form, with one or more other atoms. In logic polyvalence refers to inexact, or approximate, reasoning. In other words, it is not binary. In either case, I think that this is the best we can do right now when discerning what his choice of the name indicates. This seems to suit his character as he is both quiet, unassuming, and simple as well as firm, decisive, and eloquent when he speaks.

In the true Catholic spirit, I have to go with Assisi/Xavier/de Sales, and/and/and, not either/or/or. It seems to me that the thread that weaves together the three Francises is being a missionary. This also links his papacy, at least to some extent, to that of Benedict XVI. Francis of Assisi, a missionary whose task, given him by our Lord, was to rebuild, that is, reform the Church. St. Francis Xavier who traveled far and died on Shangchuan Island, where he was waiting to continue his missionary journeys by taking the Gospel of Jesus Christ to the Chinese mainland. His other missionary destinations included Japan, Indonesia, and India. St. Francis de Sales, of course, was the Counter-Reformation bishop of Geneva, the city of Calvin, a master communicator, and so also a missionary who lead many back to the Catholic faith.

In his brief remarks, he said: "And now let us begin this journey, the Bishop and people, this journey of the Church of Rome which presides in charity over all the Churches, a journey of brotherhood in love, of mutual trust. Let us always pray for one another. Let us pray for the whole world that there might be a great sense of brotherhood . My hope is that this journey of the Church that we begin today, together with help of my Cardinal Vicar, be fruitful for the evangelization of this beautiful city." Being a missionary, I can only take him to mean ab urbe, ad mundi (i.e., from the city to the world).
